You jog 3.6 miles and 30 minutes at that rate how long will it take you to jog 4.8 miles

3.6 / 30 = 4.8 / x ... 3.6 miles to 30 min = 4.8 miles to x minutes

cross multiply because this is a proportion

(3.6) (x) = (30) (4.8)

3.6x = 144

x = 144/3.6

x = 40 minutes ... so it would take 40 minutes to jog 4.8 miles

It will take you 10 min. more
